🧮Variables

🧮 Variables let you reuse values across a workflow without repeating them.

Variable types

• Start input: The value passed by the trigger, such as a customer message. Read it with <start.input>.
• Workflow variables: Constant values you define once and use in any step.
• Secrets: API keys and credentials stored securely and referenced without exposing their values (see Platform → Secrets).

Reference syntax

Reference values by name, such as env.CRM_API_KEY for secrets, or use connection tags like <blockName.field> for step outputs.

🔐 Never write secret keys directly inside steps. Always use Secrets so Wkil keeps their values out of logs and content.
